The invention discloses a rail transit composite material transverse handrail and a manufacturing process thereof, and the rail transit composite material transverse handrail comprises a transverse handrail straight pipe and transverse handrail bent pipes fixedly connected with the two ends of the transverse handrail straight pipe; the transverse handrail bent pipe is connected with a car roof through a connecting support; the outermost layer of the transverse handrail straight pipe in the section direction is a first shear-resistant layer, the innermost layer is a second shear-resistant layer, and the middle layer comprises a bending-resistant layer and a compression-resistant balance layer. The first anti-shearing layer and the second anti-shearing layer are made of woven fiber composite materials, the anti-bending layer is made of 0-degree laying fiber composite materials, and the pressure-resistant balance layer is made of 90-degree laying fiber composite materials. The rail transit composite material transverse handrail prepared by the invention can give full play to light weight and weight reduction effects, can reduce the weight by more than 65% under the condition that the manufacturing cost is equivalent to that of an existing metal handrail, and has a good weight reduction effect; and meanwhile, the force bearing requirement of the rail transit transverse handrail is met.
